this does't need multiple backends (we have multiple settings for theming already: themes), and the colour should come out of the theme color scheme so it can be matched properly to the panel.

at the very least this can form the basis of the defaults; i'm unconvinced this needs to be configurable, since the idea is to at least replace the default black background for themes that don't provide opaque/ svg's (which is the proper route for themes)

My idea is that there would at least a few configurable background-providers: User-chosen solid color(with alpha value), user-chosen pattern(tinted by solid color with alpha-value), solid color autodetected from the background image(to make the colors match).
